The 99.95ms fixed latency is horrible. The same quick hack (of not disabling tsched in BATCH mode) appears to work for me. Now I get "configured latency: 16.00 ms; range is 16.00 .. 743.04 ms". Note that if I use module-jack-sink I get a fixed latency of 2.67ms (as configured by jack), so the hardware can do much better than 16ms, just not directly from module-alsa-sink. What can we do to fix this?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
